از دوستان كسي ميتونه يه توضيح مختصري درباره nvidia cuda بده؟يه محيط برنامه نويسي براي gpu هست؟كه بشه برنامه هاي مختلف رو با gpu پردازش كرد؟

دوست عزیز قسمتی از متن توضیحی کمپانی ان وی دیا درباره این برنامه رو براتون ترجمه کردم واصلش رو هم در اختیارتون قرار میدهم.

تکنولوژی CUDA کمپانی ان وی دیا تنها محیط برنامه نویسی زبان C جهانی هست که نویسندگان و توسعه دهندگان برنامه ها رو در نوشتن نرم افزار ها برای حل مشکلات محاسباتی پیچیده در بخشی از زمان و البته به لطف قدرت پردازش موازی چند هسته ای جی پی یو ها قادر میسازد. با وجود میلیونها جی پی یو سازگار با Cuda که از قبل عرضه شده هزاران تن از نویسندگان برنامه ها با استفاده از ابزار نرم افزاری رایگان CUDA قادر به سرعت بخشیدن به اجرای برنامه ها شدند و از جمله اکتشاف نفت و گاز با استفاده از کد گذاری صدا و تصویر و طراحی محصول و عکس برداری های پزشکی و پژوهش های علمی.

NVIDIA CUDA™ technology is the world’s only C language environment that enables programmers and developers to write software to solve complex computational problems in a fraction of the time by tapping into the many-core parallel processing power of GPUs. With millions of CUDA-capable GPUs already deployed, thousands of software programmers are already using the free CUDA software tools to accelerate applications—from video and audio encoding to oil and gas exploration, product design, medical imaging, and scientific research.

TECHNOLOGY FEATURE

Standard C language for parallel application development on the GPU

Standard numerical libraries for FFT (Fast Fourier Transform) and BLAS (Basic Linear Algebra Subroutines)

Dedicated CUDA driver for computing with fast data transfer path between GPU and CPU

CUDA driver interoperates with OpenGL and DirectX graphics drivers

Support for Linux 32/64-bit and Windows XP 32/64-bit operating systems

این ابزار جالب اورکلاک که توسط ZOTAC رونمایی شده و نیترو نام دارد اطلاعات بسیار خوبی رو در نمایشگر خودش از جمله سرعت فن کارت گرافیک و دمای کارت همچنین مموری کلاک و کلاک هسته و کلاک سایه زن را در اختیار کاربر قرار میدهد.

ضمن اینکه این ابزار اورکلاک قابلیت اورکلاک مموری و هسته و سایه زن رو داره.این ابزار ساده و جالب اورکلاک کارت گرافیک احتمالا در پایان ماه اکتبر سال جاری میلادی قابل عرضه میباشد و بیشتر احتمال بر این هست که به همرا کارتهای های اند این کمپانی عرضه بشه و باز احتمال این هم هست که به صورت جدا عرضه بشه و قیمت حدودیش برای عرضه در اروپا 89 یورو و برای ایالات متحده امریکا در حدود 99 دلار هست.

پیروز باشید

Info-Tek GECUBE, the renowned Taiwanese graphics card maker, released the HD4850 Overlocking series with a Zalman fan onboard in July. This proved a great success on the market thanks to its spectacular gaming and video playback performance. To capitalize on its popularity among enthusiasts and consumers, The GECUBE team has now developed a more advanced offering in the form of the HD4850 1.0GB Overclocking series. The new HD4850 1.0GB Overclocking series includes an exclusive ceramic fan that delivers not only an ultra-quiet working environment, but also extreme performance. The new card also comes with the RV770PRO 2nd generation 55nm chipset, the PCI-Express 2.0 interface, full support for DirectX10.1/SM4.1 and ATI CrossFireX technologies but also built-in HDCP, HDMI, Blu-Ray and HDVD decoder support.

Japanese PC cooling specialist, Scythe released the "Musashi" SCVMS-1000 VGA cooler spotted at a Japanese store. This double-fan aluminum cooler suits all popular card designs although the GeForce GTX 200 series isn't advertised.

The cooler consists of an aluminum fin arrays of unequal sizes through which pass four nickel-plated copper heatpipes, two in opposite direction of the other two. The GPU contact block from which those pipes project out itself isn't in the center. On one the other side of the fin arrays are two 100 mm, 12 mm thick PWN controlled fans which have individual speed controls provided by two knobs on an expansion bracket. These regulate the speeds of the fans between 800 and 2500 rpm (combined noise level 12.5 dB to 29.22 dB depending on the fans' rpm).

ASUS Released Non-Reference Radeon HD 4870 with Expanded Power Circuitry

ASUS has released a non-reference version of the ATI Radeon HD 4870 graphics card. The model is called EAH 4870 D5 and it's main difference is the enhanced power circuitry. The card uses a 4 phase vGPU power circuit along with a 2 phase vMem circuit, making it similar to that of the PowerColor HD 4870 PCS+, while the reference design uses 3 + 2 phases. The PCB uses a 100% conductive polymer capacitor design. The same Qimonda memory chips as those used on reference design boards rounds up the card.

The card runs at reference speeds of 750 MHz Core / 900 MHz Memory. ASUS used its signature Glaciator Fansink cooler for the GPU, which can already be found on many of their other cards but decided to leave the memory chips without active or passive cooling. Expreview notes that the heatsink on the MOSFETs looks small and could be a cause for concern since temperatures of that zone of video cards in general could reach as high as 110 degrees Celsius. The card uses single slot expansion bracket though the card itself requires two slots worth space due to the heatsink. This release follows several other designs from the likes of Palit, PowerColor, etc., that have similar power circuitry, presumably to facilitate better overclocks though poor cooling designs implemented by these AIBs mar the effort put in to design these superior PCBs.

البته من شنيدم كه كامپايلر اين زبان بر پايه c++ ميباشد.نه اينكه خودش شبيه c++ باشد.

Geforce 280 GTX SLI vs HD 4870 Cross Fire

در مقایسه اول مشاهده می شود HD 4870 در حالت Cross fire در دررجه بالای تنظیمات جزئیات بازی (در Directx 9) اختلاف بسیار کمی با Geforce 280 GTX در حالت SLI دارد

اما در مقایسه بعدی که درجه جزئیات بازی بیشتر شده (در Directx 10) و طبیعتا فشار بر روی کارتهای گرافیکی بیشتر شده است و بر این اختلاف بین این دو VGA افزوده شده است .

Gigabyte might well be the first AIB partner for ATI to release the first passively cooled Radeon HD 4850 accelerator, and a 1 GB one at that. The Gigabyte GV-R485MC-1GH sports the RV770 graphics processor clocked at 625 MHz and 1 GB of GDDR3 memory clocked at 1.00 GHz. Gigabyte is to use its "Multi-Core" passive cooler that consists of two arrays of aluminum fins, with two copper heatpipes each conveying heat from the core to the fin arrays. The card will feature Ultra Durable 2 high-grade electrical circuitry with what vaguely looks like a 4 + 2 phase power design. The GV-R485MC-1GH will be available soon. Word is that PowerColor would follow Gigabyte with their passively cooled Radeon HD 4850 model.

رضا جان ظاهرا GF9800 GT تفاوت چندانی در کارایی با GF8800 GT ندارد و در اکثر تستها نتایج برابری رو داشتند و در تعداد کمی از بنچمارکها 9800 جی تی برتری ناچیزی رو داشته.

Pre-release 3DMark tests show that two Radeon HD 4670 graphics cards in Crossfire multi-GPU mode outperforms a single Radeon HD 4850 card. The HD 4670 cards score just a little above the HD 4850 in three tests that include 3DMark06 in Shader Model 2.0 mode, the same benchmark in SM 3.0 mode and 3DMark Vantage.

The cards scored 54xx 3DMarks in SM2.0 and 65xx 3DMarks in SM3.0 tests, a 4850 on the same test-bed produced 49xx and 57xx respectively. With 3DMark Vantage, the Crossfire setup churned out 7300, with the single HD 4850 just 100 points behind at 7200. These scores can be attributed to the raw texturing power the HD 4670 cards have despite memory bandwidth advantage staying with the single HD 4850. Indications are that the HD 4650 won't scale as well since (at least reference models) lack hardware Crossfire.
